Definitions

  • the invention relates to a sports device consisting of a right and a left short ski-like scooter with a carrier as a base for the user's shoe, a shoe holder and a front and rear wheel attached to the carrier on an axis and a braking device formed from a brake and actuating device.
  • Sports equipment has already been developed which allows at least some of the movement sequences to be simulated or carried out.
  • skateboard-like devices have been created in which short-ski-like carriers are provided with rollers and thus at least permit the corresponding movement sequences for cross-country skiing.
  • the previously known sports equipment almost all have the same structure as, for example is known from DE-GM 89 04 308. They have a carrier as a base for the user's shoe, a shoe holder similar to a ski binding and a front and rear wheel attached to the carrier on an axle. Two wheels are often also provided at the rear.
  • these previously known devices have a braking device comprising a brake and an actuating device, the latter being accommodated in the ski pole and being connected to the brake, for example by a Bowden cable.
  • the invention is therefore based on the object to further improve such sports equipment of the generic type, to make it safer, to manufacture it with less material and thus more cost-effectively and to be able to adapt it to the various requirements such as maneuverability, high-speed driving or the toughest loads in uneven terrain.
  • the new sports equipment should also offer a variant of roller skates and ice skates.
  • This extremely complex task is achieved according to the invention with a sports device in which the axles for fastening the wheels and the wheels themselves are arranged within the longitudinal extent of the carrier. As a result of this measure, the sports equipment is shortened considerably compared to the known state of the art and is therefore considerably less expensive. Of greater importance is the maneuverability and the increased safety and robustness due to the compact design.
  • the diameter of the wheels are within the longitudinal extent of the carrier, so that they protrude in front and back with only small segments of a circle.
  • the axles to which the wheels are attached are arranged immediately below the carrier, and the diameter of the wheels is such that there is at least 1/4 of the diameter of the wheels above the top of the carrier.
  • a wheel diameter between 10 and 20 cm has proven to be very useful. On the one hand, this wheel size is large enough to provide sufficient running comfort, considerable speeds, sufficient cushioning and, above all, also to enable inclinations, as are common in turns and similar movements that are modeled on skiing.
  • this dimensioning ensures that the wearer is close to the ground, that the center of gravity of the sports equipment is low, and that tilting to the side and serious falls are avoided.
  • the carrier is preferably assembled from profile tubes, so that very simple and easily accessible construction materials can be used. So an expedient embodiment is that two longitudinal spars and cross connectors are joined together and result in a very stable support, between which one wheel is inserted at the front and one at the rear.
  • the construction of the carrier from profile tubes enables a further advantageous embodiment of the sports device, which makes it possible to use a device for a large number of people, for example the members of a family or for members of a sports club with different shoe sizes, in which the profile tubes extending in the longitudinal direction of the sports device divided and are held in diameter so that they are telescopically pushed into each other and thus adapted to the required shoe size.
  • Profile tube parts of the same diameter serve the same purpose if they are connected to each other by means of a longer clamp.
  • the carrier is formed from a U or T profile, which is associated with the advantage that the contact surface for the shoe is particularly stable.
  • the carrier is designed in the front and rear as a fork, so that the wheels can be accommodated within the carrier, but leave the middle part in one piece.
  • the shoe holders are slidably mounted on a guide rail of the profile tube or the U or T profile, so that with in a few simple steps, expediently by loosening screws, the shoe holders can be loosened, their spacing changed by moving them and fixed again in the desired position by tightening the screws.
  • Another expedient possibility of adjusting the distance of the shoe holder is to introduce a number of positioning holes into the carrier and thus to bring about the adjustability.
  • At least one of the shoe holders has a Velcro fastener element on the upper side, which has a Velcro counter element on the underside of the shoe, preferably under the sole and under the heel, together creates a Velcro fastener.
  • This Velcro fastener there are considerable simplifications in handling, improvements in the use of the sports equipment, but especially a much more versatile application of the sports equipment.
  • the Velcro in the manner described above makes a single piece of sports equipment usable for different users with different shoe sizes. There is also a considerable saving in warehousing for retailers because the entire device no longer has to be kept in stock in all common sizes. In the case of the sports device with the Velcro fastener described, only one size is required for the sports device itself and only the shoes have to be kept in stock in the usual sizes. Another advantage of the use of a Velcro fastener in the sports equipment is that the shoe is held firmly and every foot movement takes place without slippage and thus the movements carried out by the user are transferred directly to the sports equipment.
  • Another advantage is that the separation of shoe and sports equipment enables the Velcro fastener to be released quickly by prying it off, for example to walk uphill on your shoes alone, to put the sports equipment on your shoulders and only to put it back on when that Permits off-road driving.
  • the braking device known in the basic principle, in which an actuating device, preferably a handle, expediently also in conjunction with a ski pole a connecting line to the brake, advantageously in the form of a Bowden cable, the brake is actuated.
  • the actuation can advantageously also take place by means of electronic control via a remote control.
  • the brake can advantageously be arranged on both sides of at least one of the wheels.
  • This symmetrical arrangement is particularly advantageous when high speeds are intended with the sports equipment without significant changes in direction.
  • the brake on both sides is even recommended on both wheels so that you can brake quickly and come to a standstill.
  • the power transmission to the brakes is advantageously carried out via a scissor lever attached below the carrier, which is expediently provided with spreading springs which release the brakes again when the actuating device is released.
  • At least one of the wheels is provided with a brake, which is advantageously arranged on the outside.
  • This embodiment has the advantage of being inexpensive and of attaching the brake where it is particularly effective for the desired movement sequences and least disturbing in terms of construction.
  • the brake is expediently designed as a band brake and engages the Wheels.
  • the brake acts directly on the rotating axles that carry the wheels.
  • the sports device In the sports device according to the invention it is essential that only one front wheel and one rear wheel are present in order to understand turns and similar movements of skiing. There is, of course, a certain instability in each front and rear wheel, especially for the inexperienced user, with which every beginner has to struggle when skating, for example, and which includes the risk of tipping and slipping away.
  • a particularly preferred development of the invention is to arrange the front and rear wheels asymmetrically to the longitudinal axis of the carrier. This is associated with the advantage that the sports equipment has a considerably better overall stability and above all with regard to the risk of tipping over, without the expense and the restriction of the mobility of a 4-wheel arrangement having to be accepted.
  • the improvement in the stability of the sports equipment and the prevention of unwanted tilting movements and slipping sideways can advantageously be achieved in that the middle part of the carrier on which the shoe rests is shifted towards the ground with respect to the wheel axles, the position of which is predetermined by the wheel diameter and thus the focus of the sports equipment as a whole.
  • the displacement of the middle part of the carrier towards the floor enables a further advantageous embodiment of the sports equipment in such a way that the carrier is guided upwards at both ends in an arc or angle and the wheels are fastened in an axle fork which is guided through the ends of the carrier or is otherwise connected to the ends of the carrier, for example by means of clamps.
  • the axle fork can expediently be made in two parts, so that the length of the axle fork is variable in that the diameter of both parts is held in this way are that they can be telescoped.
  • axle fork In the case of a two-part axle fork with the same diameter, this variability in the length of the axle fork can be effected using clamps or sleeves in which the parts of the axle fork abut one another or have a certain distance between their ends if a somewhat longer axle fork is required.
  • the axle fork is advantageously mounted in shock absorbers, so that this embodiment of the sports device is particularly suitable for use outside of paths and slopes in undulating terrain.
  • the mobility and the adaptation to movements of skiing, roller skating and skating is promoted by an advantageous variant of the invention, which is based on the fact that the axis of at least one of the wheels is designed as a sliding axis, with one or two springs expediently the wheel into the Press the normal position so that, for example, a staggered position of the front and rear wheel results in a stabilized position, as is usually the case with four wheels.
  • the wheel When making turns, i.e. Shifting the body weight to one side, on the other hand, the wheel is moved towards the carrier while compressing the spring, while the spring pushes it outwards again when straightening and driving straight ahead.
  • the formation of at least one of the axes as a curve-sliding axis has proven to be particularly outstanding, in that one or both wheels are ball-bearing on a sliding sleeve, with compression springs expediently supporting the wheel when running straight ahead in the Stabilize the middle.
  • the wheel slides on the curve sliding axis by means of the sliding sleeve, thus making it easier to master the curve and change direction.
  • the sliding axis or curve sliding axis are advantageously equipped with a lock, by means of which they can be deactivated, so that the wheels only run centrally, as is expedient when the force is accelerated.
  • the utility value of the sports device can be further increased in an advantageous manner by additional equipment such as lights, speedometers, tachometers, and odometers. Since it cannot be ruled out that the lateral outer areas of the carrier will come into contact with the ground during turns and when cornering, it is expedient to protect these outer areas by wear-resistant coverings which are advantageously interchangeable.
  • Fig. 1 to 3 shows the basic structure of a sports device with braking of both wheels 4, 5 on both sides.
  • the carrier 1 consists of a skiboard-like base plate with the two-part shoe holder 6 for holding the shoe 20.
  • the two wheels 4, 5 are arranged within the carrier 1 and fastened to axles 2, 3 and have brakes 15 on both sides in the form of disc brakes. which are connected to the respective actuating device 24 in the form of a handle via the Bowden cable 21 and the scissor lever 23 provided with spreading springs 22.
  • the arrangement of the wheels 4, 5 and the axles 2, 3 within the carrier 1 results in a very compact design.
  • the carrier 1 is formed by two longitudinal bars 13 and two cross connectors 14.
  • a front Velcro fastener 25 and a rear Velcro fastener 26 are used to put on the carrier 1 and connect it to the shoe 20, which is mounted somewhat higher in the manner of a heel in shoes in order to better adapt the position of the shoe 20 to the natural position of the foot.
  • the vertical fixing of the shoe 20 on the carrier 1 takes place via tensioning straps 27.
  • a brake 15 in the form of a band brake is arranged on the outside only on the front wheel 4.
  • FIGS. 6 and 7 differs from that of FIGS. 4 and 5 in that the carrier 1 ends in the front and rear in a fork 16 between which the wheels 4 and 5 and the axles 2 and 3 and the front wheel 4th the one-sided brake 15 are inserted.
  • the Velcro fastener use is also made of the Velcro fastener, only one of the two interacting Velcro elements, namely that fastened on the shoe holder 6, being shown in FIG. 6, but the reference numerals 25 and 26 have also been retained for this.
  • FIG. 8 to 11 show the asymmetrical arrangement of the wheels 4, 5 on both sides of the carrier 1 with a brake 15 acting on one side on the front wheel 4 in the form of a band brake.
  • the Bowden cable 21 in FIG. 9 is fixed on the carrier 1 by means of a Bowden cable cable guide 28.
  • the adjustability of the shoe holder 6 is possible by moving it along the guide rail 7 on the carrier 11, in FIG. 11 by fixing it via the positioning holes 8 in the carrier 10.
  • axis 2, 3 is provided with a spring joint 17, which serves the suspension of the wheels 4, 5, in particular on uneven terrain.
  • axles 2, 3 arranged inside the carrier 1, here in the form of an inverted U-profile 10, are extended to the side and designed as a sliding axis 19 on which the wheel 4 or 5 can slide, and by one Spring 18 is pressed into the outer position.
  • Fig. 14 the carrier 1 is shifted towards the ground, so that it is at approximately the same height with the wheel axles 2, 3. At both ends, the carrier 1 is guided upward in an arc and is fastened to the axle fork 29 with a clamp 33.
  • the axle fork 29 is made in two parts, the two parts interlocking telescopically and forming a shock absorber 30.
  • the lower part of the axle fork 29 is fork-shaped and receives the axles 2, 3 between the fork 16, on which the wheels 4, 5 are fastened.
  • the front wheel 4 can be braked via a brake 15 in the form of a band brake, the actuation being effected via the Bowden cable 21.
  • the carrier 1 is in two parts, and both parts are dimensioned in diameter so that they are telescoped, so that the distance between the shoe holder 6 can be changed in this way.
  • the profile tube part of the carrier 1 with the further diameter has a slot 12 at the end, so that after setting the required length of the carrier 1 and thus the required distance between the shoe carriers 6, the clamp 9 can be tightened and the two profile tube parts are thus fixed in their position relative to one another .
  • 16 shows the design of the axle as a curve sliding axle 19a, the wheels 4, 5 being mounted on balls 32 on a sliding sleeve 31 and being laterally displaceable against the force of compression springs 34.
